People with normal blood sugar range may be at increased risk of brain shrinkage

People whose blood sugar is on the high end of the normal range may be at greater risk of brain shrinkage that occurs with aging and diseases such as dementia, according to new research published in the September 4, 2012, print issue of Neurology-, the medical journal of the American Academy of Neurology.

PRISM technique as accurate as ELISAs in identifying proteins within biological samples

Combining two well-established analytic techniques and adding a twist identifies proteins from blood with as much accuracy and sensitivity as the antibody-based tests used clinically, researchers report this week in Proceedings of the National Academy of Sciences Early Edition online.

Scientists succeed in clarifying molecular signature of hantaviruses

Scientists at Charité - Universitätsmedizin Berlin and Labor Berlin GmbH have succeeded in clarifying the molecular signature of the viruses that lead to an increasing size and number of hantavirus outbreaks in Germany.

Gene therapy approach restores ability to smell in mouse model of congenital anosmia

Scientists funded by the National Institutes of Health have restored the ability to smell in a mouse model of a human genetic disorder that causes congenital anosmia-the inability to smell from birth. The approach uses gene therapy to regrow cilia, cell structures that are essential for olfactory function.

Heavy alcohol use rewires brain circuitry and increases risk of PTSD

Doctors have long recognized a link between alcoholism and anxiety disorders such as post-traumatic stress disorder (PTSD). Those who drink heavily are at increased risk for traumatic events like car accidents and domestic violence, but that only partially explains the connection. New research using mice reveals heavy alcohol use actually rewires brain circuitry, making it harder for alcoholics to recover psychologically following a traumatic experience.

Metabolic syndrome associated with cognitive and brain impairments in adolescents

A new study by researchers at NYU School of Medicine reveals for the first time that metabolic syndrome (MetS) is associated with cognitive and brain impairments in adolescents and calls for pediatricians to take this into account when considering the early treatment of childhood obesity.

Missing link between bone marrow stem cells and human immune system

UCLA researchers have discovered a type of cell that is the "missing link" between bone marrow stem cells and all the cells of the human immune system, a finding that will lead to a greater understanding of how a healthy immune system is produced and how disease can lead to poor immune function.

MDA7 compound shows promise against Alzheimer's disease

A compound developed to treat neuropathic pain has shown potential as an innovative treatment for Alzheimer's disease, according to a study by researchers at Cleveland Clinic's Lerner Research Institute and Anesthesiology Institute.

FSU researchers achieve significant benchmarks in alpha-tropomyosin study

Florida State University researchers led by physics doctoral student Campion Loong have achieved significant benchmarks in a study of the human cardiac protein alpha-tropomyosin, which is an essential, molecular-level component that controls the heart's contraction on every beat.

Scientists restore sense of smell in mice through gene therapy

Scientists have restored the sense of smell in mice through gene therapy for the first time -- a hopeful sign for people who can't smell anything from birth or lose it due to disease.

DEAD-box proteins function as recycling nanopistons when unwinding RNA

AUSTIN, Texas-Molecular biologists at The University of Texas at Austin have solved one of the mysteries of how double-stranded RNA is remodeled inside cells in both their normal and disease states. The discovery may have implications for treating cancer and viruses in humans.

Digested coconut oil able to attack the bacteria that cause tooth decay

Digested coconut oil is able to attack the bacteria that cause tooth decay. It is a natural antibiotic that could be incorporated into commercial dental care products, say scientists presenting their work at the Society for General Microbiology's Autumn Conference at the University of Warwick.

Scientists create mathematical model that helps to design new drug cocktails against HIV

For years, doctors treating those with HIV have recognized a relationship between how faithfully patients take the drugs they prescribe, and how likely the virus is to develop drug resistance. More recently, research has shown that the relationship between adherence to a drug regimen and resistance is different for each of the drugs that make up the "cocktail" used to control the disease.

Potential new COPD drug

A study led by researchers at Boston University School of Medicine (BUSM) has shown that a compound used in some skin creams may halt the progression of emphysema and reverse some of the damage caused by the disease. When the compound Gly-His-Lys (GHK) was applied to lung cells from patients with emphysema, normal gene activity in altered cells was restored and damaged aspects of cellular function were repaired.

Seven antibiotic-resistance genes swapped between human and soil bacteria

Soil bacteria and bacteria that cause human diseases have recently swapped at least seven antibiotic-resistance genes, researchers at Washington University School of Medicine in St. Louis report Aug. 31 in Science.

Study establishes association of IL-16 with prostate cancer in African-American men

Prostate cancer in African-American men is associated with specific changes in the IL-16 gene, according to researchers at the University of Illinois at Chicago College of Medicine.

Study shows how NCAN gene results in manic symptoms of bipolar disorder

Flying high, or down in the dumps - individuals suffering from bipolar disorder alternate between depressive and manic episodes. Researchers from the University of Bonn and the Central Institute of Mental Health in Mannheim have now discovered, based on patient data and animal models, how the NCAN gene results in the manic symptoms of bipolar disorder. The results have been published in the current issue of "The American Journal of Psychiatry."

NFAT protein plays a part in development of acute pancreatitis

It is likely that the protein is also highly significant for other inflammatory diseases. The research results have been published in the American journal Gastroenterology.

Boosting immune system can help reduce asthma attacks due to viral infections

Details of a treatment that could help asthmatics fight infections that trigger 80% of asthma attacks, developed by University of Southampton spin-out company Synairgen, will be presented to European respiratory experts on Sunday 2 September.

New intriguing knowledge on blood haemoglobin

Scientists at the research centre MEMBRANES at Aarhus University, Denmark, have completed an old puzzle, which since the 60s from many sides has been regarded as impossible to complete. The challenge was to solve the structure of the protecting protein complex that forms when haemoglobin is released from red cells and becomes toxic. This toxic release of haemoglobin occurs in many diseases affecting red cell stability, e.g. malaria.
